Preparing to connect the PV generator
↻ PV generator checked to ensure there is no ground fault.
↻ A connection cable with 2 x 1 or 2 x 2 cores is available on the device.
1 For improved accessibility: Remove the DC attachment plate by undoing the 4
fastening screws [ T_30].
2 Undo the cable fitting for DC connection [ W_46]
3 Remove the sealing plug in the cable fitting used.
4 Remove the outer cladding of the DC cables.
5 Insert the DC cables into the cable fittings.
6 Strip the insulation from the DC cables pursuant to the M10 ring cable lug so
that the stranded wire and insulation can be pushed into the shaft of the cable
lug.
CAUTION! Risk of fire due to chemical corrosion. Cable lugs must be suitable
for the conductor material and copper busbars used.
7 Push the ring cable lug onto DC cores.
8 Slip a shrink-fit sheath (not part of the scope of supply) over the shaft of the ring
cable lug of the DC cable.
9 For improved accessibility: Fasten the DC attachment plate by tightening the 4
fastening screws [ T_30 /
10 Connect the PV generator.
Connecting the PV generator
↻ PV generator connection prepared.
↻ DC cables equipped with a ring cable lug [max width 42 mm ].
1 Place the cable lug of cores DC- and DC+ on the busbar in accordance with the
labeling and secure it with a nut, screw and lock washer (fastening elements in
scope of supply) [ W_17 /
2 Check that the connected cables are fitted securely.
3 Tighten cable fittings [ W_46 /
» The device is connected to the PV generator.

When using aluminum cable lugs we recommend using cable lugs with galvanic tin plating or, alternatively, AL/CU ca-
ble lugs with suitable AL/CU washers.
Otherwise, with the electrolytes present (e.g. Condensation water), the aluminum could be destroyed by the copper
bus bars.
